To investigate the effect of nitrogen level on the yield and quality of watermelon(Citrullus vulgaris S. cv. Bocksubak), N levels of 250, 200, 140, and 0kg/ha with the conventional amount of K and P supply non-fertilization treatments were compared one anther. Plant height, leaf area, fresh weight and dry weight were better in nitrogen application treatments than no nitrogen and non- fertilization treatments. But there was no significant difference between nitrogen levels. Yield and fruit setting ratio were the highest in N level of 140kg/ha. Fruit weight was increased by N application, and soluble solids content was the highest as 12.5 $^{circ}$Bx in N level of 140kg/ha. Nitrogen content of leaves was increased with the applied nitrogen amount and highest at the middle stage of growth. P content was no significant difference between treatments. Ca content was increased with the applied nitrogen amount and highest at the late stage of growth.
